Did you know that catalytic converters can stop working as they age, causing your engine to belch out dangerous fumes and poisonous gas? Yes, this is the purpose of a catalytic converter: to convert the toxic byproducts of internal combustion engines to environmentally acceptable substances. When the catalyst is used up, you need a new Catcon. Designed to meet or exceed GM emissions requirements, our genuine OEM replacement part Catalytic Converters will return your Cadillac STS exhaust emissions to correct levels. Properly selected and installed, they are compatible with emissions standards in 49 states (excepting California) and guaranteed to get your Caddy back to factory specifications in time for the emissions test. Why pay more for the same item? Genuine OEM parts are PartsGeek.com's stock in trade. This official Cadillac replacement part will add new life to your Cadillac STS and help provide years of worry-free driving pleasure.


They are available for the following Cadillac STS years: 2007, 2006, 2005, 07, 06, 05. This part is also sometimes called Cadillac STS Exhaust Converters. We stock catalytic converter parts for most Cadillac models including DeVille, CTS, SRX, Escalade, DTS, Eldorado, Allante, Brougham, Catera, Seville, Fleetwood, Commercial Chassis and Cimarron.

We stock these Catalytic Converter brands for the Cadillac STS: Eastern Catalytic, Magnaflow and DEC.

Parts were as described and correct. Shipped on time as promised. The web site was easy to use and I was able to quickly find what I needed in comparison to some competitor sites. Tracking information contained in the order confirmation e-mail is helpful. The merchant clarified that the restocking fees are waived in the event of order errors on their part per the FAQs on their site.
